问题描述
限时送ChatGPT账号..我使用的是 Xcode 4.5 和 iOS 6.0,我从 xcode 中选择了默认的单视图模板,我只想在应用程序窗口上添加标签,但我无法这样做.请纠正我.
I am using Xcode 4.5 and iOS 6.0, I have selected the default single view template from the xcode, I just want to add the label on the application window but I am unable to do so. Please correct me.
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
self.window.rootViewController = self.viewController;
label =[[UILabel alloc] initWithFrame:CGRectMake(100, 100, 200, 20)];
label.text = @"Test";
[label setBackgroundColor:[UIColor whiteColor]];
[self.window addSubview:label];
[self.window bringSubviewToFront:label];
[self.window makeKeyAndVisible];
return YES;
}
PS - 我希望我的标签在我的 ViewController 视图之上,即在窗口上,所以尽管窗口呈现的视图发生了变化,它仍将始终存在.我不想在这里只显示标签.
PS - I want my label on top of my ViewController view i.e. on the window so it will be always there despite changes in the views presented by window. I dont want to only show the label here.
我得到了答案
[self.window.rootViewController.view addSubview:label];
谢谢大家指点.
推荐答案
只需删除 RootviewController
.
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
label =[[UILabel alloc] initWithFrame:CGRectMake(100, 100, 200, 20)];
label.text = @"Test";
[label setBackgroundColor:[UIColor whiteColor]];
[self.window addSubview:label];
[self.window bringSubviewToFront:label];
[self.window makeKeyAndVisible];
return YES;
}
如果您不想只在此处显示标签,请使用如下所示.
if you dont want to only show the label here then use like below.
self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
self.window.rootViewController = self.viewController;
[self.Viewcontroller.view addSubview:label];
